FILLING-STATION VALVE AND KEY.

Application filed March l0, 1926.

This invention relates to trilling stations for supplying automobiles and other vehicles with gasoline. the station being oll the type employing a measuring pump and an underground Storage tank having pipe connection to the pump.

More particularly the invention relates to :i valve and operating key therefor.

In stations ot' this class the pipe connection between the tank and pump is usually either valveless or is provided with :1 valve having' an ordinary operating handle easily arresaible above the ground. iuch constructions lead to ready thet't ol' the gasoline durn ing the ab ence ot the attendant either b v automobiliets or operators ol' nearby stations. the latter especially beingI able to keep watch on the attendant, note his absence and visit the station and remove more or less gasoline unlawfully'.

(ne object of the present invention is to provide an improved arrangement of station oll this character wherein the pipe eonnection between the tank and pump will be provided with an underground valve having its .litem equipped with a lsperially formed head which cannot be turned withouty the use of a specific eoolrierating key which is inserted in a pipe or tube leading from the surface ot the ground to such valve.

A second object ot the invention is to provide an improved form ot valve head arrangement so constructed as to permit of a large number ot' variants whereby only one key forni will lit any particular valve stein head to operate the valve.

A third object of the invention is to iinprove the general arrangement. of filling stations of the class described.

lVith the above and other objects in view as will be hereinafter apparent, the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings and specilically claimed.

In the accompanying drawings like characters of reference indicate like parts in the several views, and:

Figure 1 is a general elevation, partly in section of a filling station constructed in accordance with the invention.

Figure 2 is an enlarged detail showing a portion of the tank and the filling and gauging p1pes.

Serial No. 93,789.

Figure il is a detail perspective ot' the gauge rod guide member.

Figure 4 is an enlarged section on the line bwl ol' l` `igure l.

Figure 5 is a side elevation ot the valve key used herewith. a portion ot' the shank being broken out to permit the view being ofl' proper scale.

l `igure ti is a side elevation, partly in seetion showing one t'orm of valve stem head.

Figure i' a side elevation showing a second form ot' valve stem head.

l1`igure b is a sertion through a portion ot' one torni of key head.

Figure l is a group end view ot one set ot keys ot one Igeneral type.

Figure 5) is an end view of a valve stein head corresponding to the lir-`t of the key heads shown in Figure i).

Figures lt) to 2t) are similar end views showing dititrently modilied types otE keye, but one key ol' each set being shown.

ln the embodiment oil the invention herein ehown it will be seen thatV there is provided a mersuring pump 1t) here indieated in e'eneral outline only since anyY well known torni ol" pump ma)v be used in eonneet'ion with this: invention and alo because the particular construction ot sneh pump lorms no part: ot' the present invention.

The ground is indicated aty G and buried in the ground is a storage tank 11 which may be ot any convenient torni or size as is best adapted for the particular lilling station. Extending upwardly from a snitable point at the top of the tank is a vertical pipe 12 and from a point in the length of this pipe extends an L-shaped branch pipe 13 having one arm of the L extending up to the surface of the ground, being there provided with a removable cap 11. l'hii pipe 13 and the lower end of the pipe 12 constitute the tank filling pipe. Screwed into the top of the pipe 12 is a coupling member 15 having an upwardly extending threaded boss .16 and extending longitudinally through this member and bons is a rectangular slot of sufficient size to receive and guide a measuring or ullage rod (not shown Screwed on the boss 16 is a measuring rod guide tube 18 which projects somewhat above the ground and is providedv with a removable Cap 19.

Connecting the tank and pump is a supply pipe 2O and this pipe runs principally under-- ground. At a point in the underground l tl length of this pip-e there is provided a 'sontrol valve 21 which is preferably of the (liek type :ind is provided with :i itein (ln this stein iS mounted a cylindrical head 23 which may be secured to the Stern by brew ing or solder shown :it 2l in ltigiure G or by Serevvdnmv the heard on the Stent :ind there locking itY by n hwk nut Q5 :ind roller 2G. llendiuo; up l'roni the vulve to the sur face of the, `round is :i key lube 2T` they tube beirut;h held in ponitiion ou the vidve by :i 'trup 28 und lniviuy,v the unuzd removable cup Q9.

Thus only the proper key eun be used lo turn any particular valve und it will be #een that the blade and pin arrangement nifty be `greatly varied so that there may be a wide range to the number ot keys und vulve stein heads which will Cooperate only when the proper key und head are brought together. Thus :i given vulve can be opened only by :L definiteA key.
